NOTE: These are games that are in development but are not yet published. This means the games, at the time I reviewed them, were not even in alpha stage yet. Some of them may not even have an alpha/beta and head straight to publication as stated on their FAQs. When they change status, I shall remove them from here and put them in the appropriate page.
Stardew Valley: An RPG+Simulation game that I could best describe as a Harvest Moon/Terraria love child. There are many things you can do in the game solo or with your friends (it offers a 4 player co-op). From maintaining a farm to fighting beasties in dungeons, this game will satisfy your RPG and Simming needs.
